Described herein are systems, methods, and apparatuses for time synchronization for nodes in a wireless personal area network (WPAN). A first message can be received, via an advertising channel, from an advertising node of a WPAN, the first message comprising an advertising message and a message identifier. A second message can be received from a timekeeper node of the WPAN, the second message comprising the message identifier of the first message and timestamp information identifying a time the second message was received by the timekeeper node. A time offset value can be calculated for a clock circuitry with respect to the advertising node, the time offset value comprising a difference between a time the first message was received by the receiver circuitry and the timestamp information of the second message. The clock circuitry can be adjusted based, at least in part, on the time offset value. |
